                      Nested if Statement

                 JavaScript allows the nested if statement. This means the if indented block inside another if…else
                 indented block. The second nested if indented block will run only when the first if condition evaluates
                 to be true. The syntax of nested if statement is shown below:
                 Syntax:


                 if(condition 1)
                 {

                     if(condition 2)
                     {

                          //When the condition 1 and condition 2 is true then block of
                 code to be executed.
                     }

                     else

                     {
                          //When the condition 1 is true and condition 2 is false then
                 block of code to be executed.

                     }
                 }

                 else
                 {

                     //When the condition 1 is false then block of code to be executed.

                 }



                                                                                 Conditional Statements in JavaScript  85
